N. Y., A CORPORATION. OF DELAWARE MACHINE-UN IT SUPPORT AApplication led April 11,

4it isdesirable to isolate such vibrations from the surrounding structure as far as possible. Many attempts have been made to provide what is in eiect a Heating mounting, but the diiiiculty of maintaining a suiiciently rugged and strong mounting without permitting too great displacement between the machine and the floor has presented problems which have not,v as yet, been successfully solved. The present invention relates to a mounting for a machine wherein the deleterious vibrations are deadened sufficiently to relieve the surrounding structure from the weakening effects thereof, at the same time preserving an extremel rugged and positive mounting. The speci c design and details of the mounting structure will be described more fully in connection with the accompanying drawings wherein:

Figure 1 is a view in section, taken on line 1-1 of Figure 2 and looking in the direction of the arrows. n

Figure 2 is a view in section, taken on line 2-2 of Figure 1 and lookingin the direction of the arrows.

Figure 3 is a view in elevation, showing the cushioning element which deadens the vibrations transmitted from the machine to the floor or base.

In the above drawin a desi ates a bracket which is secure to a mac line and serves as a means for mounting it upon the Hoor. n

This bracket is formed with an extension a having an aperture a2 through which a bolt b may extend. Spaced nuts c, threaded on the bolt b, engage the extension a and secure the bracket and machine in a desired position.

Bolt b is providedwith an extension b having a restricted and threaded portion b2. A disk-shaped foot d is screwed on the threaded portion b2 and provides upper and lower bearing surfaces for a block e of yielding, non-metallic material, such as rubber.

1928. Serial No. 269,259.

If desired, this block may be formed in two parts to facilitate the mounting ofthe bolt, in which case the block could be split in a horizontal plane. A two part housing formed with an aperture f to receive the extension b and the block of yielding, nonmetallic material e. This cushioning material is placed under a predetermined degree' of compression by means of bolts g, some of which may extend through the housing and secure it to the floor, or base h. After the extension b and disk-shaped foot d have been inserted in the cushioning material e, thelatter is placed within the housing f and the bolts ,g are tightened. The bracket is then placed on the bolt b and adjusted to the proper position b means of nuts c.

In order that t e cushioning material may be protected from oil and deleterious matter, a ange z' is formed on the bolt b to prevent oil from following the metal into the rubber. Cooperating with the flange is a bead lc formed around the aperture of the housing to prevent any oil drip from running into the housing.

The specific bearing member received by the yielding, non-metallic material may be formed in many shapes and, if desired, may be formed integral with the bolt extension b. Likewise the housing design and related structure maybe adjusted to accommodate various shapes or sizes of cushioning elements, in accordance with the requirements of individual installations and no limitation is to be placed upon the invention, save as defined in the appended claims. y

We claim as our invention:

1. A support for a machine comprising a housing, including an apertured cover, a bracket, a member carried by the bracket and extending through the aperture, yielding, non-metallic material in the housing, means to secure the housing to a base and simultaneously place the yielding, non-metallic material under compression, means to secure the end of the member in the yielding, nonmetallic material, a flange carried by the said member and extending over the a erture and a bead formed about the perip ery of the aperture.

2. A device yfor supportin a machine on a base, comprising a housing geving a portion adapted to abut against the base and an apertured cover portion adapted to cooperate with the rst named portion to form an interior closed except for the aperture, a. bracket, a member carried by the bracket and extendin through the a erture, yielding, non-meta lic material in t e housing, common means external of the housing to secure the cover to the housin to place the yielding, non-metallic materia under compression and to secure both portions of the housing to the base, and an enlarged portion on the end of said member seated in and surrounded by the yielding, non-metallic material.
